Gas getting into the oil - '82 GS1100E

Nice looking bike, and I dig that Youhimura exhaust- yes, its aftermarket.
You should also verify that the jetting in the carbs has been changed to compenate for the exhaust. Others here are far more knowledgable in that regard then I am.
 
That's an aftermarket exhaust, alright. And I don't think much if anything needs to be done to the carbs when installing a 4-into-1. Pods are a different matter - rejetting required.

Welcome to the 1100EZ club!

PS I think it's recommended to remove the air box lid, under the seat, when installing 4-into-1 pipes. As far as I know, on this particular model, that's the only mod to the intake.

First thing I would do when going to a 4 into 1 is put new plugs in it and run it about 100 miles or so and then check the plugs. Some regular condition riding will show up on the new plugs as to how rich or lean she is acting inside the jugs. Cheap start off point BEFORE throwing parts and more money at it.
 
Thanks all, much appreciated. I'm planning a carb-rebuild once I have a good space to do so.

Valve adjustment also sounds like a must from all the posts I've read. I'll start there, and new plugs, too, since that's pretty easy to do anyway.
 
Do the valves first before you do the final carb sync. The valve adjustment does effect the carb synchronization.
 
Okay, first off, valves were adjusted and the bike runs much better. She used to vibrate quite terribly and lose a lot of power around 65 mph. The vibration is way down, and power delivery is pretty smooth even on the top end She's not perfect yet, but that was obviously a necessary step. How often should I have to do that to the bike moving forward?

She still idles high after being run a while. She still seems to be a little lean in running. I'll at least need to balance the carbs, if not rebuild them. I'll plan on rebuilding them once I move to another apartment and hopefully have a better location to do it.

I think all my gas in oil problems stemmed from leaving the petcock in the prime position. It hasn't been having the same issue yet.

And I didn't know to look when I bought it, but she seems to have some rust in the gas tank - which can lead to all sorts of issues, I hear.
 
Also rebuilt the carb, and performed a rough bench sync. Still need to do the dynamic sync. I'm going to replace a few gaskets along the way while I'm at it. I would much appreciate any pointers on dismantling the engine to get at the head and base gaskets.

Also, I found out that my exhaust pipe colouring (see pics) were explained by a faulty petcock, and my R/R was fried, and it looks like my battery is questionable.

She needed a whole lot of work.
